WIRING SUBWOOFERS (DUAL AMPS)

When using dual amplifiers to power one subwoofer, the Positive terminal of the Subwoofers 
voice coil is connected the positive terminal of the MASTER Amplifier and the Negative terminal 
of the Subwoofers voice coil is connected to Positive terminal on the SLAVE Amplifier. This 
procedure will allow the total power of both amplifiers to be added together and act like a single 
powerful amplifier. Please check that your subwoofer power handling capabilities  are not exceeded

CAUTION

Always check your speaker load with a multi-meter before hooking up to the amplifier. These 
digital amplifiers are only 1 ohm stable. Any Impedance (load) smaller than 1 ohm will damage 
the amplifier. Such Damage is not covered under warranty either, so pay strict attention to what

 when hooking two amplifiers to it.

connections are made to the amplifier.
